-## What Was Added (All marked with "# NEW"):
-
-1. ✅ **Store embeddings** - Keep reference for future use
-2. ✅ **IndexFlatIP** - Changed from `IndexFlatL2` to `IndexFlatIP` for cosine similarity
-3. ✅ **Normalize embeddings** - Required for cosine similarity to work
-4. ✅ **Normalize query** - Query must also be normalized
-5. ✅ **Search more results** - Get 2x TOP_K to filter from
-6. ✅ **Filter by threshold** - Only keep results ≥ MIN_SIMILARITY_SCORE
-7. ✅ **Limit to TOP_K** - After filtering, keep only top K
-8. ✅ **Handle no results** - Return empty if nothing matches
-9. ✅ **Add scores to results** - Include similarity scores in dataframe
-10. ✅ **Sort by score** - Best matches first
-11. ✅ **Better logging** - Show score range

-## Impact on Accuracy:
-
-**Before:**
-```
-Query: "نسبة الحضور"
-Results: 5 chunks (some irrelevant, scores unknown)
-```
-
-**After:**
-```
-Query: "نسبة الحضور"
-Results: 3 chunks (all relevant, scores: 0.72 - 0.85)
